To a, whom, it may concern:

Be it known that I, VICTOR POPP, a citizen of the Republic of France, residing at the city of Paris, France, have invented certain new and useful Improvements in Automatic Separators for Compressed-Air Systems, of which the following is a specification.

The said invention has been patented in foreign countries as follows: in France No- IO vember 11, 1887, No. 186,823; in England November 18, 1887, No. 15,878, No. 15,878, and No. 15,878; in Germany December 24, 1887, No. 47,546 and No. 44,745; in Belgium May 7, 1888, No. 81,725, and in Italy June 30, 1888,

I 5 Vol. 40, No. 247.

My invention pertains to an automatic separator for draining the moisture from com pressed air or analogous fluid in a distribution system; and it consists in details which are shown in the accompanying drawings, in

which- Figure 1 isa vertical section; and Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a section on line 8 8 of Fig. 1.

In this separator the air enters at f in the cast-iron cylinder A and strikes against deflecting-plate B, leaving the water carried by it upon the wire screen 0. The water goes through the wire screen, which retains any solid matter which may obstruct the tubes and valves. This water accumulates at the lower part D of the cylinder. The bottom E, which is secured to A, is connected with a pipe F, closed by cock G. Its upper surface 3 5 is furnished with a circular projection H, on which is screwed a small cylinder K, of which the upper part forms a semi-spherical bowl'l, the cover to the bowl being formed by a plug M, screwed into cylinder K. At the top and bot- 40 tom of thebowl T respectively are two circular openings q, forming the seat of two conical valves a. These two valves are connected by a rod 0, which, lengthened above, is fixed to the top of a float P, made of cork or other wood. This valve-rod is guided into the cover of the pipe R, which has at its lower end a perforated bell-shaped enlargement seated on plug M, and from thence extends upward into the central opening of the float P. The water collected at D, being under the pressure of the compressed air, exerts upon the upper part of the valve a a pressure tending to keep it closed. The same pressure, but in an opposite direction, is exerted upon the lower valve by the water flowing through an opening (Z,

(shown in dotted lines,) which communicates with cavity 0 beneath valve a. This connection is more clearly shown in Fig. 3, whichis a horizontal diam etrical section through bowl T. In this figure q is the conical opening forming the seat for lower valve a. This opens into the cavity 0 below the bowl, which communicates by transverse tube (1 with the intermediate space between cylinderK and the outside wall of A. The accumulated wa ter in the lower part of A, having the pressure of the air above it, exerts a considerable downward pressure on upper valve to, conr municating therewith through the perforations in the lower end of tube B. At the same time this water communicates through tube (Z and cavity 0 with lower valve C6 and exerts thereon an upward pressure, counterbalancing its downward pressure on the upper valve.

If only the upper valve were employed, it would have above itthcinternalor compressed air pressure of the pipe system acting through the water, while it would have below it only the external atmospheric pressure of bowl T. The float wouldin that case have to overcome the pressure of the compressed air before it could lift the valve, which would be quiteimpracticable. I therefore neutralize this internal pressure by means of the lower valve to, which is oppositely exposed to the said. internal pressure. 1) 1), Figs. 1 and'i-i, are two holes establishing communication between bowl T and drain-pipe F. Then these pressures are balanced, as described, the valves do not move; but when the water has attained acero tain level the float P is raised and carries with it the valves c a, by means of the rod 0, thus opening communication between the water accumulated in the separator and the drainpipe Fthrough bowl T and passages b b. The

water then flows until its level, being lowered,

allows the float to reach its normal position an automatic outlet-valve consisting; of a float and the valves consequentlyregaintheirseats. I, and a counterbalanced valve operated by A cock G is fixed 0n the d rain-pipe l which the Heat and provided with a screen, through may be opened or closed at will. which passes the actuating valve-rod, sub- 5 I claimstantially as described. 4
